AspectSnap

Capture webpages or selected regions with custom aspect ratios, quality, and resolution limits.

AspectSnap is a professional-grade screenshot utility designed for designers, developers, and creators. It allows you to take pixel-perfect snapshots of full webpages, viewports, or custom rectangular selections with advanced layout constraints. Key Features: • Configurable Pixel Magnifier Loupe: Multi-level zoom loupe (4×, 6×, 8×, 12×) active while drawing or dragging selection handles, complete with a crosshair, pixel grid, live HEX/RGB color preview, coordinate readouts, and dimensions for sub-pixel precision. Easily adjust zoom on the fly with the mouse wheel, keyboard shortcuts (+ / - / Z), or by clicking the interactive zoom badge. • Clickpoint-Anchored Selection: New selections start directly at the clicked coordinates instead of resetting to the top-left corner of the viewport. • Text & Content Selection Protection: Automatic prevention of underlying page text and element selection when dragging selection borders to viewport edges. • Aspect Ratio Locks: Enforce 16:9, 4:3, 1:1, 3:2, or 21:9 constraints dynamically while drawing selections. • Smart Export Dimensions: Specify a target width or height and let the extension proportionally scale the image. • Dimension Mode Options: Choose between scaling any selection size to fit your target export dimensions, or using a “Fixed capture window” to capture an exact size centered region (no resizing needed). • Dimension Locking Safeguard: Restricts Viewport and Full Page export settings to width OR height only, protecting captures from aspect ratio distortion. • High-Performance Formats: Export directly to WebP, PNG, or JPG formats with optimized memory-efficient processing. • Quality Controls: Tweak compression sliders (from 10% to 100%) to optimize file size. • Smart Scroll-and-Stitch: Automatically scroll through long webpages, convert sticky/fixed elements so they are captured exactly once at the top, and compile them into a single high-definition image. • Live Capture Progress Indicator: Displays real-time progress percentage badges (0% to 99%) directly on the extension icon during full-page captures. • Offscreen Clipboard Engine: Reliable copy-to-clipboard functionality powered by a dedicated offscreen document, eliminating browser window focus errors even during long captures or when DevTools is open. • In-Page Status Toasts: Elegant, non-intrusive feedback toasts for success, warnings, and errors directly on the active page. • Preserves Save As Folder Memory: Intelligent delegated download flows trigger the native Save As dialog while correctly remembering your previously selected folder instead of resetting to the default Downloads folder. • Rate-Limit Throttling: Respects Chrome’s system screenshot limits, allowing captures on extremely long pages without crash events. • Modern Theme support: Clean, responsive layout that automatically adapts to Light or Dark modes. How to use it: 1. Open the extension popup from your toolbar. 2. Select your capture mode (Viewport, Selection, or Full Page). 3. Set your constraints, format, compression, and output size. Click “Capture Screen” (or press Alt+Shift+S for quick selection capture). 4. Draw or adjust your selection with the configurable pixel magnifier loupe (scroll mouse wheel to zoom), and hit Snap! Privacy Note: All image processing, cropping, and compression happen entirely locally within your browser using modern Web APIs. AspectSnap does NOT collect, store, or transmit any user data or webpage content off-device.
